This example reproduces a Sol LeWitt art piece using two overlapping masks to create a circular interplay of horizontal and vertical stripes. The SVG canvas displays 100 horizontal bands and 100 vertical bands, each masked to reveal a clear circle in the center. The code constructs SVG elements programmatically, using `createElementNS` for the `rect` and `mask` nodes, and applies the masks via `url(#circle-mask)` and `url(#circle-mask-2)`. The piece demonstrates geometric abstraction through simple, repeating shapes and clipping.
